You want to find out which sport the students at your school like the best. You go to the first football game and stop every 5th student entering the main gate and ask which sport is his or her favorite. Is this a representative sample of the students at your school? A
yes, because you are asking a variety of students

B
no, because you would need to ask every person who goes to the football game, not just every 5th

C
no, because the sample is biased—it only includes students who go to football games

D
yes, because every 5th person makes it random

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake

12r - 8 - 12

12r - 8 - 12

together it combines to:

12r - 20

hope this !
